6.35: a) The static friction force would need to be equal in magnitude to the spring force, kd mg = μ s or 76 . 1 ) s / m 80 . 9 )( kg 100 . 0 ( ) m 086 . 0 )( m / N 0 . 20 ( s 2 = = μ , which is quite large. (Keeping extra figures in the intermediate calculation for d gives a different answer.) b) In Example 6.6, the relation 2 1 2 k 2 1 2 1 mv kd mgd = + μ was obtained, and d was found in terms of the known initial speed 1 v . In this case, the condition on d is that the static friction force at maximum extension just balances the
